list_file_snapshots

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden. It discloses that the tool shows snapshot time, modified files, and AI summaries, but does not explicitly state it is read-only or describe any side effects. The verb 'list' implicitly signals a safe operation, but additional behavioral detail (e.g., no modifications, return format) would strengthen transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the action and key differentiators (AI-enhanced, easy rollback selection). It adds relevant detail without redundancy or fluff.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with no output schema, the description adequately covers the core behavior and the content of the returned data. It could mention the default limit or the availability of filters, but those are already in the schema, so the description is sufficiently complete for an agent to invoke correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for all four parameters (limit, format, filePath, sessionId), so the baseline is 3. The description does not add any parameter-specific meaning beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb+resource ('List AI-enhanced file snapshots') and adds purpose context ('for easy rollback selection'). It clearly distinguishes from sibling tools like list_project_snapshots and restore_file_snapshot by focusing on the listing behavior for file snapshots.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies a clear use case: when you need to select a file snapshot for rollback. It does not explicitly name alternatives or exclusions, but the context of 'rollback selection' is concrete enough to guide an agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
